Description

Technical Field

[0001] The invention relates to the technical field of belt conveyor accessories, and in particular to a novel intelligent hydraulic deviation correcting device. Background Art

[0002] Belt conveyors are a type of bulk material conveying equipment widely used in industries such as coal, metallurgy, mining, ports, chemicals, light industry, petroleum, and machinery. The equipment has the characteristics of a wide range of applicable materials, large transport capacity, high climbing ability, low operating costs, easy use and maintenance, and easy to realize the automatic control of the transportation system. Therefore, belt conveyors are widely used in the bulk material conveying industry. However, due to the long conveying distance, the non-central distribution of the carried materials, and the uneven installation accuracy, the belt conveyor is prone to cause the belt to deviate, resulting in material scattering along the line, damage to the conveyor belt, and shutdown, affecting the daily production. Among them, the deviation caused by the non-central distribution of the carried materials is difficult to correct. The method of preventing the belt from deviating in the industry is mainly to change the displacement of the belt conveyor roller and install a correction device along the belt conveyor. At present, the existing correction device mainly corrects the deviation of the belt through friction. When the belt deviates, the correction device changes the angle between the axis of the roller and the axis of the belt conveyor to generate a force that forms an angle with the running direction of the belt conveyor, thereby generating friction to make the belt run in the center. However, the angle that can be changed by this deviation-correcting device is small, the friction force is limited, and it is impossible to center the material that is not centered.

[0003] For example, a highly efficient deviation correction device and correction method for rollers on a belt conveyor with publication number CN113548377A includes a roller assembly, a transmission assembly, an actuator assembly, a sensor assembly and a control system; the sensor assembly is arranged on the roller assembly to collect the lateral pressure of the roller assembly on the sensor assembly when the roller assembly deviates; the sensor assembly is data-connected to the control system to transmit the lateral pressure data of the roller on the sensor assembly to the control system; the control system is signal-connected to the actuator assembly; the actuator assembly is drive-connected to the transmission assembly; the transmission assembly is drive-connected to both sides of the roller assembly, and the transmission force of the actuator assembly is transmitted to the roller assembly through the transmission assembly, and the roller assembly is adjusted to move to adjust the deviation of the roller assembly. This solution senses the deviation of the roller assembly through the sensing assembly, and connects the actuator assembly and the transmission assembly through the control system to drive the roller assembly to move and correct the deviation, which greatly improves the efficiency of deviation correction during operation of the belt conveyor.

[0004] In practical applications, the above technical solution has the problems of small deviation correction range, limited friction force and inability to process non-centered materials.

[0005] Therefore, it is necessary to invent a new intelligent hydraulic deviation correction device to solve the above problems. Summary of the invention
